## Polymath15, second thread: generalising the Riemann-Siegel approximate functional equation

This is the second “research” thread of the Polymath15 project to upper bound the de Bruijn-Newman constant, continuing this previous thread. Discussion of the project of a non-research nature can continue for now in the existing proposal thread. Progress will be summarised at this Polymath wiki page. We now have the following proposition (see […]
